BTW, you'd have to find the IDQ 8s on ebay or other sites, they've been discontinued.

"jonathan, now you got me thinking again. perhaps koda 8's in the doors and a nice set of 4" comps in kicks? shallow crossover slopes would allow for better off-axis performance right? if i were to use an electronic crossover with adjustable slopes, should i use a 6db slope b/w the midbass and the comps or would that slope need to match the one in the components' crossover? and what slope would be best to use on the low end of the midbass? something steeper or same as the upper end?
sh1t, i dont know. i should probably get a good set of two-ways but this is interesting stuff to know"

Steeper slopes offer better off axis performance. Shallow slopes are a bitch to get positioned right, especially 6db/oct. But from a SQ standpoint, it's the more preferable slope assuming you aren't doing a lot of high volume listening. If you want really good off axis performance I'd recommend 18 or 24db/oct. The HPF for the tweeter is generally a minimum 12db/oct to limit it's excursion as frequencies get lower, with a 3" or 4" midrange I'd recommend the same for the same reason as the tweeter. Didn't see that the Koda 8" was discontinued, Dayton makes good 8" midbass drivers though. A pair of Image Dynamics IDQ 8s would be awesome :) . In all honesty though, the 2 way idea is generally optimum in most vehicles. If you want 3 ways, DLS, Dynaudio, CDT, Focal, Rainbow, and others all offer great 3 way component sets.

that'll work

fishy, thanks, definitely let me know how that sounds.

i just went to adire's website and saw that the new product line is out. http://www.adireaudio.com.
looks like they jacked up the prices on the shivas :( and unless i'm missing it or they havent put it on the website yet, they dont make an 8" driver anymore!
damn, that Maelstrom 15 looks like a mean sub.

Agree with Kiki about the Platinums, though :D You'll nearly cream yourself when you hear them.

If I were to add midbass up front, I'd personally do something like Adire Koda 8s instead of the dual 6.5" drivers. It would blend together very well with the soundstage and add a little more depth, which is perfect if you want to get a stronger sub (such as that Avalanche you plan) because you can crossover lower. But then again, if I were to go to the extent of doing 3 ways with a dedicated 8" midbass, I'd put a dedicated midrange driver in kicks like a 3" or 4" midrange driver instead of the 5.25", such as those in the Dynaudio, DLS, CDT, and other high end 3 way sets, that way you will get a driver with better off axis performance and a smoother upper midrange, and it is easier to mount, provide airspace for, and angle properly.

I'm doing some 6w0's in the rear of my Explorer and plan on running them from about 70-200(maybe 80-250) and run my front 5 1/4's highpassed at 200Hz 6dB/oct.

Soon as my Knukonceptz order gets here I'll give you an update on how it sounds.

awesome. bandpass at 200hz-2khz ok?

by GlassWolf » Thu Apr 28, 2005 5:34 pm

with a bandpass filter, and wired in mono as midbass drivers, no you won't mess up the soundstage if the front stage is strong. remember, it'd just be midbass behind you, and that's mostly out of vocal range and fairly non directional.

by J.W. » Thu Apr 28, 2005 2:55 pm

in the back would be ok? that would be easier. i'd rather do that, but i thought that would mess up the imaging more than putting them in the front? it wouldnt pull the soundstage to the rear? i guess if i ran them in mono and bandpass them with the lowpass at about...i have no idea?...then it wouldnt be too bad huh?
